I'm on the phone with Rogers right now and they confirm that they have been having network outages in downtown Toronto today. Also, they tell me that some of my network connection problems today are due to the fact that I don't have a 4000-series SIM card. The 2.1 update caused a conflict with my old SIM card, according to them. So I have to go get a new one. Can anyone tell me, did your iPhone come with a new SIM card in it? The CSR who sold me my iPhone (over the phone) asked me whether I wanted a new one or not. I said no, and would swear my iPhone came with a fake cardboard SIM card in the tray. Please tell me I didn't throw away a real SIM card!
